Towards a physical understanding of the thermal background in large ground-based telescopes
Leonard Burtscher, Ioannis Politopoulos, Sergio Fernández-Acosta +11
Ground-based thermal-infrared observations have a unique scientific potential, but are also extremely challenging due to the need to accurately subtract the high thermal background…
Design, pointing control, and on-sky performance of the mid-infrared vortex coronagraph for the VLT/NEAR experiment
A. -L. Maire, E. Huby, O. Absil +16
Vortex coronagraphs have been shown to be a promising avenue for high-contrast imaging in the close-in environment of stars at thermal infrared (IR) wavelengths. They are included…
The quantum efficiency and diffractive image artifacts of Si:As IBC mid-IR detector arrays at 5 10 m: Implications for the JWST/MIRI detectors
Andras Gaspar, George H. Rieke, Pierre Guillard +6
Arsenic doped back illuminated blocked impurity band (BIBIB) silicon detectors have advanced near and mid-IR astronomy for over thirty years; they have high quantum efficiency (QE)…
Extreme Universe Space Observatory on a Super Pressure Balloon 1 calibration: from the laboratory to the desert
J. H. Adams, L. Allen, R. Bachman +63
The Extreme Universe Space Observatory on a Super Pressure Balloon 1 (EUSO-SPB1) instrument was launched out of Wanaka, New Zealand, by NASA in April, 2017 as a mission of opportun…
The LOFAR Two Meter Sky Survey: Deep Fields, I -- Direction-dependent calibration and imaging
C. Tasse, T. Shimwell, M. J. Hardcastle +29
The Low Frequency Array (LOFAR) is an ideal instrument to conduct deep extragalactic surveys. It has a large field of view and is sensitive to large scale and compact emission. It…
MIRISim: A Simulator for the Mid-Infrared Instrument on JWST
P. D. Klaassen, V. C. Geers, S. M. Beard +18
The Mid-Infrared Instrument (MIRI) on the James Webb Space Telescope (JWST), has imaging, four coronagraphs and both low and medium resolution spectroscopic modes . Being able to s…
High contrast at small separation -- II. Impact on the dark hole of a realistic optical set-up with two deformable mirrors
M. Beaulieu, P. Martinez, L. Abe +3
Future large space- or ground-based telescopes will offer the resolution and sensitivity to probe the habitable zone of a large sample of nearby stars for exo-Earth imaging. To thi…
Mini-EUSO mission to study Earth UV emissions on board the ISS
S. Bacholle, P. Barrillon, M. Battisti +57
Mini-EUSO is a telescope observing the Earth in the ultraviolet band from the International Space Station. It is a part of the JEM-EUSO program, paving the way to future larger mis…
The LSST DESC DC2 Simulated Sky Survey
LSST Dark Energy Science Collaboration, Bela Abolfathi, David Alonso +77
We describe the simulated sky survey underlying the second data challenge (DC2) carried out in preparation for analysis of the Vera C. Rubin Observatory Legacy Survey of Space and…
Fast algorithms to approximate the position-dependent point spread function responses in radio interferometric wide-field imaging
M. Atemkeng, O. Smirnov, C. Tasse +2
The desire for wide-field of view, large fractional bandwidth, high sensitivity, high spectral and temporal resolution has driven radio interferometry to the point of big data revo…
Deep Generative Models for Galaxy Image Simulations
Francois Lanusse, Rachel Mandelbaum, Siamak Ravanbakhsh +3
Image simulations are essential tools for preparing and validating the analysis of current and future wide-field optical surveys. However, the galaxy models used as the basis for t…
Characterizing the accuracy of ALMA linear-polarization mosaics
Charles L. H. Hull, Paulo C. Cortes, Valentin J. M. Le Gouellec +9
We characterize the accuracy of linear-polarization mosaics made using the Atacama Large Millimeter/submillimeter Array (ALMA). First, we observed the bright, highly linearly polar…
Spacecraft and interplanetary contributions to the magnetic environment on-board LISA Pathfinder
M. Armano, H. Audley, J. Baird +79
LISA Pathfinder (LPF) has been a space-based mission designed to test new technologies that will be required for a gravitational wave observatory in space. Magnetically driven forc…
